Specification of Letters Patent.

original application filed. May 13, 1910, Serial ,No. 561,035. Dividedend this application fil ed January 19,

To all whom. it may concern.-

Be it known that we, DAVID H. COLES and FREDERICK CrmnAvAY, citizens of the United States, residing at New York, county of New York, State of New York, and at Jersey City Heights, county of Hudson, State of New Jersey, respectively, have invented certain new and useful Improvements in- Rotary Distributing Valve-Bodies, of which the following is a specification, reference being; had therein to the accompanying drawing.

This invention is a rotary distributing valve-body for use in internalcombustion and other engines.

The object of the invention is to produce "a valvebody which may be mounted in a proper cylindrical encasement suitably connected with engine cylinders; the valve-body being of a construction to receive and to distribute the gaseous or other mixture received by it, appropriately for high eiii- -ciencv 111 a two-cycle orother engine,

In he accompanying drawings, Figure l is a side view, and Fig. 2 a lengthwise, cen tral sectlon at line 9 -9 of Fig. 1, of our new valve-body. Fig. 3 is a rear elevation of a casingwhich contains a lengthwise-extending compression-chamber surrounding a ro tary valve casing. This view shows ports for connection with three cylinders, and also shows water-jacket ports. Fig. 4 is a top plan view of said casing. 'Fig. i3 is a front elevation of said casing. Figs. '6 and 7 are lengthwise central complementary sections at line of Fig. l of said casing, the rotary valve being removed. It is also removed from Figs. 3, 4; and 5. Fig. 8 is a lengthwise central. View of the assembled casing and rotary valve, the latter being in one of'its positions of use. This view also shows operating mechanism for the valve,

and further shows ports for connection with an intake ,manifold not shown. Referring to'the drawings, the valve-body 21 is round in some, and partially..round in other cross-sections, to form bearing walls a: and bearing collars 26, here shown, with one exception, as circumferentially grooved to receive gaskets that are not shown. The end walls of the rotary valve-body are indicated by y, and these end walls are provided with intake ports 35. From the end walls gain the particular form of valve-body Serial No. 672,049.

7 shown, the bearing ends 20 of the valve-body oppositely project. The valvebody is lengthwise chambered between its end walls and its circumferential wall :0 is formed with a plurality of exit ports :23, which are preferably, and as shown, in staggered relation one to another, and spaced apart one from another. Through these exit ports the or fluid, received into the lengthwise chamber through the opposite inlet ports 35 in opposite ends of the valve-body, is dis charged (into a pump, not shown). The circumferential wall of the lengthwise chamber depressed at 24, opposite each exit port 23, and the valve-body is provided with circumferentially extendingv grooves 24, the space of each of which communicates with the space of a depression 2a. The function of each communicating space of a depression 24, and ofa circumfercntially extending groove 24:, is to receive (gas from a pump cylinder, not shown) and discharge the gas or other fluid when the valve-body is assembled with other parts (into a transfer chamber, not shown, whence the gas goes tothe working cylinder of an engine, not shown). Each exit port 23 is surrounded by a wall bearingsurface, in part consisting of a portion 90 and in part of a collar 26; and, circumferentially considered, wall bearing portions 00 space the mouth of each exit port apart from the opening or mouth of the space in a depression 24., intervening between the openings of said spaces, so as to separate said openings one from another when the valve-body is mounted in a cylindrical casing. The functions of the collar portionsQG are not only to form good circumferential bearing surfaces intermediate the ends of the valve-body, but in the present construction, also to form a side. wall of a groove 24. \Vhile, in the form of valvebody illustrated, only three exit ports and Patented Sept. 15, 1914.

the circumferentially extending grooves 2 1 may be varied. In fact, the form of our new valve may be varied, without departure from our invention, in many respects, to suit difi erent styles or forms of engine construction. 4

Referring to Figs. 3 to 8, inclusive, casing A is adapted for attachment in the form shown to three engine cylinders, as

shown in our Patent No. 1,020,128 of March 12, 1912, of the applicationfor which, this present application'is a division. It contains a water-jacket chamber and ports 39 not material to the invention but shown; and its rear side is formed with three upper ports 16, one for each piston cylinder; and with three lower ports 17, one for each pump cylinder, as described in said patent. Casing A contains the gas-transfer chamber 10 in which more or less gas compression may occur, but a function of which is to collect the gas from the pump cylinders and to distribute the gas to the piston cylinders, as required. Chamber 10 may be also considered as a gas-storage chamber. It is formed by the end and outward walls of easing A and by the lengthwise-extending interior wall 22 which is intei'iorly round in cross section and serves as a hearing or housing for the rotary valve 21. Casing A. is open on its front side as shown .in Fig. 5, and this opening is closed gas-tightly by a cover. The rotary valve casing is provided with four ports a spaced 'apart around its circumference and each directly communicating with one of the spaces 24 of the rotary valve. The adjacent group of ports 7), arranged-similarly to ports (1, directly commiinicate with one of the spaces '24: of the rotary valve and another group of similarly arranged ports 0, directly communicute with the ren'iaining space 24 of the rotary valve, all the ports as shown, pertaining to a thrcerylindcr engine. Gas is taken into the opposite ends of the rotary valve through its ports 35 which communicate with the ports 35 of casing A. 'l. he parts indicated by 10 are merely stud-like pieces of metal between the outward wall of c: sing A and wall 22.

\Vhat we claim, is,-

'1. A rotatable valve-body having an exteriorly round, bearing surface; a lengthwise extending chamber the opposite end walls of which are each forincd with an inlet port and the circumferential side wall of which is formed with a plurality of exit ports, the

teriorly to said chamber another lengthwise-extending chamber inclosing the Wall of the interior chamber; thewalls of said chambers being ported for the purposes described.

2. A rotatable valve-body formed with exteriorly round bearing surface portions and between its ends with a lengthwise extending chamberprovided with a plurality of inlet ports spaced apart and a plurality of exit ports spaced apart and in staggered relatioh one to another; the circumferential 'all being depressed opposite each exit port and spaced apart therefrom by intervening wall bearing portions of the valve-bod in combination with a valve casing having an interior cross-sectiona1ly-round lengthwiseextending chamber for the valve body, and exteriorly to said chamber another lengthwise-extending chamber inclosing the wall of the interior chamber; thr walls of said chambers being ported for the purposes described.

The combination with a rotatable valve-body formed with eXt'eriorly-round' bearing surface portions, and between its ends with a lengthwisc-extending chamber provided '1111 a plurality of inlet-ports spaced apart, and a plurality of exit-ports spaced apart and in staggered relation one to another; the circumferential wall being depressed opposite each exit-port and space apart therefrom by intervening wallbearing portions of the valve-body; of a casing comprising an exterior gas-chamber ported for connection with a plurality of engine cylinders, and an interior rotary valve' chamber ported for connnunication with said exit ports.

In testimony whereof we our signatures in presence of two witnesses.
